Question: what animals vomit and poo smells the worst ??

Birds’ poo doesn’t usually smell much so I get it easy there! The vomit of a seabird (the biggest the worst) can be really disgusting though, it smells like rotten fish mixed with oil. Usually we put the vomit samples in alcohol and that makes it smell even worst. The first time I spent a whole morning sorting out vomit samples, I then went for luch and asked for a fish dish but when they put the fish on the table I realised I couldn’t possibly eat it because it reminded me of the smell of the vomit! I never did that mistake again.
Still, the worst vomit and droppings smell I ever came across were those from my children when they were babies, so being a scientist was handy because it prepared me a little bit for that.
